First off, I like the haunted aesthetic presented. The sound effect and bg ambiance were unsettling and provided an interesting atmosphere. I'm also impressed that you managed to put together a project like this using Pygame in under 5 days. Good choices in the environmental design and technical execution department!
Now onto some critiques! As mentioned by others, the fact that bats aid you and wolfs kill you is not clear. This led to frustration on my end when I landed on the wolf for the first time after clearing the fire jump. There are a couple of ways you could go about fixing this, but the simplest would be to just make the bat look like it can help you. Maybe it could carry a platform on ropes, or have a board on it's head for you to stand on.
The second problem I noticed was the difficulty of the gameplay. It felt like I was playing a level designed for much later in the game. The two areas I noticed being overly difficult in timing were the fire jump from the cliff and the water jump with a block over my head. If you introduce difficult timings really early into your games, people are less inclined to continue playing due to frustration--in short, it felt unfair. You might consider adding checkpoints so that players aren't reset to zero over and over with every timing they slightly miss.
Overall, a fun spooky platformer. After I got over the high learning curve, I was able to enjoy some of the more difficult timings. With a slight tweak to the skill progression, you've got a solid platformer. Good luck with whatever you choose to do!
